How cities across the globe adapt to changing climate

Cities and coastal areas around the world are preparing to become more resilient to natural disasters and the effects of changing climate. New York City is pushing for a $20 billion system of flood barriers; Miami is working to keep "fresh water inland and salt water away;" and Venice, Italy is planning to build "Moses barriers" to fight floods. Other places, including London, Bangladesh and Bangkok are also taking steps to adapt to the changing climate.
